Social anxiety disorder, also known as social phobia, is one of the most prevalent anxiety disorders, affecting 7-13% of subjects in the community at some time in their lives. Despite being eminently treatable, it remains largely under-recognised and, therefore, undertreated. The disorder is characterized by a fear of scrutiny by others, with sufferers experiencing excessive anxiety in social and performance situations. This excessive anxiety usually leads to avoidance behaviour that can severely affect normal daily living. With onset commonly occurring during childhood or adolescence, social anxiety disorder may disrupt normal patterns of development of social and personal relationships, often having a long-term impact on emotional stability in social or working life. If left untreated, the course of social anxiety disorder is frequently complicated with comorbid conditions, particularly major depression or substance abuse. This review assesses the size of the clinical problem by evaluating current and lifetime prevalence estimates, age of onset, risk factors and evolution of the clinical course; thereby providing the rationale for early recognition and prompt treatment.

Der Beitrag untersucht auf der Grundlage neuer primärärztlicher Befunde die Versorgungsqualität bei der hinsichtlich Chronizität und Arbeitsausfall schwerwiegendsten Angsterkrankung, der Generalisierten Angststörung. Neben einer knappen Einführung in das Störungsbild werden die an über 20 000 Patienten in 558 Hausarztpraxen gewonnenen Kernbefunde der GAD-P-Studie (Generalisierte Angst und Depression in der Primärärztlichen Versorgung) zusammengefasst und Ansatzpunkte zur Verbesserung der Versorgungsqualität dieses selten adäquat behandelten Störungsbildes diskutiert. Insbesondere wird auf die zentrale Bedeutung einer sichereren diagnostischen Erkennung als Voraussetzung für therapeutische Verbesserungen hingewiesen. In Ergänzung zur Verbesserung bestehender Weiterbildungsangebote wird auf Arzt- und Patientenebene der breitere Einsatz bestehender Screeningverfahren, die Nutzung krankheitsspezifischer Patientenratgeber, sowie eine breitere Öffentlichkeitsarbeit zur Information über dieses bislang vernachlässigte, häufig chronisch verlaufende Krankheitsbild empfohlen. / Based on new empirical findings in a large-scale primary care study, the quality of care for the most chronic and debilitating anxiety problem, generalised anxiety disorder, is examined. Following a brief introduction of this disorder, the core findings of the GAD-P study (generalised anxiety and depression in primary care) with more than 20,000 patients of 558 family doctor practices are summarised and measures to improve the quality of care of patients with generalised anxiety disorder, a disorder which is rarely adequately treated, are discussed. This paper particularly emphasises the standard use of time-efficient diagnostic screening instruments, because improved recognition and diagnosis is the prerequisite for appropriate treatment. Further the role of the media to increase awareness of this disorder as well as patient education materials to improve compliance and to enhance treatment outcome effects are highlighted.

Background and Objectives: To describe patterns of healthcare utilization among patients with generalized anxiety disorder (GAD) in general practitioner (GP) settings in Germany. Methods: Using a large computerized database with information from GP practices across Germany, we identified all patients, aged > 18 years, with diagnoses of, or prescriptions for, GAD (ICD-10 diagnosis code F41.1) between October 1, 2003 and September 30, 2004 ("GAD patients"). We also constituted an age- and sex-matched comparison group, consisting of randomly selected patients without any GP encounters or prescriptions for anxiety or depression (a common comorbidity in GAD) during the same period. GAD patients were then compared to those in the matched comparison group over the one-year study period. Results: The study sample consisted of 3340 GAD patients and an equal number of matched comparators. Mean age was 53.2 years; 66.3% were women. Over the 12-month study period, GAD patients were more likely than matched comparators to have encounters for various comorbidities, including sleep disorders (odds ratio [OR] = 6.75 [95% CI = 5.31, 8.57]), substance abuse disorders (3.91 [2.89, 5.28]), and digestive system disorders (2.62 [2.36, 2.91]) (all p < 0.01). GAD patients averaged 5.6 more GP encounters (10.5 [SD = 8.8] vs 4.9 [5.7] for comparison group) and 1.4 more specialist referrals (2.3 [2.9] vs 0.9 [1.7]) (both p < 0.01). Only 58.3% of GAD patients received some type of psychotropic medication (i.e., benzodiazepines, antidepressants, and/or sedatives/hypnotics). Conclusions: Patients with GAD in GP practices in Germany have more clinically recognized comorbidities and higher levels of healthcare utilization than patients without anxiety or depression.

Objective: To examine the association between separation anxiety disorder (SAD) and mental disorders in a community sample and to evaluate whether separation anxiety is specifically related to panic disorder with and without agoraphobia. Method: The data come from a 4-year, prospective longitudinal study of a representative cohort of adolescents and young adults aged 14–24 years at baseline in Munich, Germany. The present analyses are based on a subsample of the younger cohort that completed baseline and two follow-up investigations (n = 1,090). DSM-IV diagnoses were made using the Munich Composite International Diagnostic Interview. Cox regressions with time-dependent covariates were used to examine whether prior SAD is associated with an increased risk for subsequent mental disorders. Results: Participants meeting DSM-IV criteria for SAD were at an increased risk of developing subsequent panic disorder with agoraphobia (PDAG) (HR = 18.1, 95% CI = 5.6–58.7), specific phobia (HR = 2.7, 95% CI = 1.001–7.6), generalized anxiety disorder (HR = 9.4, 95% CI = 1.8–48.7), obsessive-compulsive disorder (HR = 10.7, 95% CI = 1.7–66.1), bipolar disorder (HR = 7.7, 95% CI = 2.8–20.8), pain disorder (HR = 3.5, 95% CI = 1.3–9.1), and alcohol dependence (HR = 4.7, 95% CI = 1.7–12.4). Increased hazard rates for PDAG (HR = 4.2, 95% CI = 1.4–12.1), bipolar disorder type II (HR = 8.1, 95% CI = 2.3–27.4), pain disorder (HR = 1.9, 95% CI = 1.01–3.5), and alcohol dependence (HR = 2.1, 95% CI = 1.1–4.) were also found for subjects fulfilling subthreshold SAD. Conclusions: Although revealing a strong association between SAD and PDAG, our results argue against a specific SAD-PDAG relationship. PDAG was neither a specific outcome nor a complete mediator variable of SAD.

We examined parental psychopathology and family environment in subthreshold and DSM-IV threshold conditions of social anxiety disorder (SAD) in a representative cohort sample of 1,395 adolescents. Offspring and parental psychopathology was assessed using the DIAX/ M-CIDI; recalled parental rearing and family functioning via questionnaire. Diagnostic interviews in parents were supplemented by family history reports from offspring. The cumulative lifetime incidence was 23.07% for symptomatic SAD, and 18.38 and 7.41% for subthreshold and threshold SAD, respectively. The specific parent-tooffspring association for SAD occurred for threshold SAD only. For subthreshold and threshold SAD similar associations were found with other parental anxiety disorders, depression and substance use disorders. Parental rearing behaviour, but not family functioning, was associated with offspring threshold SAD, and although less strong and less consistent, also with subthreshold SAD. Results suggest a continued graded relationship between familial risk factors and offspring SAD. Parental psychopathology and negative parental styles may be used defining high-risk groups to assign individuals with already subthreshold conditions of SAD to early intervention programs.

Generalized anxiety disorder (GAD) is associated with painful physical symptoms (PPS). These post hoc analyses of previous trial data assessed PPS and their response to duloxetine treatment in GAD patients. Studies 1 and 2 (n = 840) were 9- to 10-week efficacy trials; study 3 (n = 887) was a relapse prevention trial comprising a 26-week open-label treatment phase and a 26-week double-blind, placebo-controlled treatment continuation phase. Mean baseline visual analog scale scores (VAS, 0–100; n = 1727) ranged from 26 to 37 for overall pain, headache, back pain, shoulder pain, interference with daily activities, and time in pain while awake. In studies 1 and 2, improvement on all VAS scores was greater in duloxetine-treated than in placebo-treated patients (p ≤ 0.01). In study 3, pain symptoms worsened in responders switched to placebo compared with those maintained on duloxetine (p ≤ 0.02). In conclusion, duloxetine was efficacious in the short- and long-term treatment of PPS, which are common in GAD patients.

Background: Subtle and inconsistent differences in hypothalamic-pituitary-adrenal (HPA) axis activity have been reported for patients with panic disorder. While these patients show little or no alterations in basal ACTH and cortisol levels, it has been hypothesized that HPA hyperresponsivity was a trait in panic patients when exposed to novel and uncontrollable stimulation. Methods: Thirty-four patients (23 females, mean age 35 yrs) diagnosed with panic disorder were compared to 34 healthy controls matched for age, gender, smoking status, and use of oral contraceptives. Both groups were exposed twice to a potent laboratory stress protocol, the Trier Social Stress Test (TSST) on consecutive days. Free salivary cortisol levels and heart rate responses were repeatedly measured before and following the TSST. In addition, the cortisol awakening response (CAR) was assessed to further investigate HPA reactivity in PD patients. Results: While the TSST induced similar heart rate stress responses in both groups, cortisol responses were clearly absent in the panic patients with normal responses in the controls (F(1.96, 66) = 20.16; p < 0.001). No differences in basal cortisol levels were observed in the extended baseline period. The same cortisol stress non-response patterns were observed when patients with/without comorbid depression, or with/without psychotropic medication were compared. In contrast to their non-response to the psychosocial stressor, panic patients showed a significant CAR. Conclusion: These findings provide strong evidence to suggest that PD patients present with a striking lack of cortisol responsivity to acute uncontrollable psychosocial stress under laboratory conditions. This unresponsiveness of the HPA axis appears to be rather specific, since a normal CAR in the morning could be documented in these patients. Thus, the present results do not support the hypothesis that PD patients show a trait HPA hyperresponsiveness to novel and uncontrollable stimulation. In contrast, the data provide support for a hyporesponsive HPA axis under emotional stress in PD patients.

This study aims to gain an increased understanding of generalized anxiety disorder based on how the target group describe their experiences. The data was gathered through podcasts where people with GAD talked about their life situation, what strategies they use to manage general anxiety and what they think relieves general anxiety. The gathered data was then analyzed through a thematic analysis where four main themes were developed; a constant worry, managing stigma, controlling or avoiding and only relive, not cure. These themes were analyzed based on Goffman's theory of stigma and Gidden's theory of the risk society. The results show that people with GAD live with a constant anxiety that affects their entire life situation, such as their work, leisure, and social relationships. Their anxiety can be likened to an allergy to uncertainty as it´s triggered by something they cannot control. They feel stigmatized by others and feel that they often need to hide their stigma by living behind a facade. To deal with generalized anxiety, three different strategies are used, which are trying to control everything, avoiding anxiety by not exposing oneself to things that cause concern or by keeping oneself busy. However, these strategies can aggravate the condition but there are many things that can relieve general anxiety. The most prominent factors are medicine, therapy, emotional support and self-help such as exercise and meditation. But the results show that the symptoms persist despite great efforts and several treatments, which indicates that more research and more effective interventions are required. The study concludes that GAD is not only a problem that exists within the individual but also in interpersonal relationships and in the society. It also concludes that there must be a change in the structures of society regarding mental illness, and that interventions should not only be directed towards the individual but also towards the relatives. This because the results show that relatives are also affected and that their influence can both aggravate and improve the individual's condition. / Den här studien syftar till att få en ökad förståelse för generaliserat ångestsyndrom utifrån hur målgruppen själva beskriver sina upplevelser. Empirin samlades in genom poddar där personer med GAD berättade om sin livssituation, vilka strategier de använder för att hantera generell ångest och vad de anser lindrar generell ångest. Materialet analyserades genom en tematisk analys där fyra huvudteman togs fram; en konstant oro, hantera stigma, kontrollera eller undvika och endast lindra inte bota. Dessa teman analyserades utifrån Goffmans stigmateori och Giddens risksamhällesteori. Resultatet visar att personer med GAD lever med en konstant oro som påverkar hela deras livssituation, så som deras arbete, fritid och sociala relationer. Deras oro kan liknas med en allergi mot ovisshet då den triggas av sådant de inte kan kontrollera. De upplever sig stigmatiserade av andra och känner att de ofta behöver dölja sitt stigma genom att leva bakom en fasad. För att hantera generaliserad ångest används tre olika strategier vilka är att försöka kontrollera allt eller att undvika ångesten genom att inte utsätta sig för sådant som väcker oro eller att ständigt aktivera sig. Dessa strategier kan dock förvärra tillståndet, men det finns mycket som kan lindra generell ångest. De mest framträdande faktorerna är medicin, terapi, emotionellt stöd och självhjälp, som exempelvis meditation och träning. Resultatet visar dock att symtomen kvarstår trots stora ansträngningar och flertalet behandlingar vilket tyder på att mer forskning och effektivare interventioner krävs. Studien konkluderar att GAD inte enbart är ett problem som existerar inom individen utan även i mellanmänskliga relationer och i samhället som helhet. Därmed dras också slutsatsen att det måste ske en förändring i samhällsstrukturerna avseende psykisk ohälsa och att interventioner inte enbart bör riktas mot individen utan även anhöriga. Detta då resultatet visar att anhöriga också påverkas och att deras inflytande både kan förvärra och förbättra individens tillstånd.

Background. To examine the role of parental psychopathology and family environment for the risk of social anxiety disorder (SAD) in offspring from childhood to early adulthood, covering an observational period of 10 years. Method. A community sample of 1,395 adolescents (aged 14 to 17 years at baseline) was prospectively followed-up over the core high risk period for SAD onset. DSM-IV offspring and parental psychopathology was assessed using the Munich-Composite International Diagnostic Interview; direct diagnostic interviews in parents were supplemented by family history reports from offspring. Parental rearing was assessed by the Questionnaire of Recalled Rearing Behavior in offspring, family functioning by the McMaster Family Assessment Device in parents. Results. Parental SAD was associated with the offspring’s risk to develop SAD (OR = 3.3, 95%CI: 1.4-8.0). Additionally, other parental anxiety disorders (OR = 2.9, 95%CI: 1.4-6.1), depression (OR = 2.6, 95%CI: 1.2-5.4) and alcohol use disorders (OR = 2.8, 95%CI: 1.3-6.1) were associated with offspring SAD. Offspring’s reports of parental overprotection, rejection and lack of emotional warmth, but not parental reports of family functioning were associated with offspring SAD. Analyses of interaction of parental psychopathology and parental rearing indicated combined effects on the risk for offspring SAD. Conclusions. These findings extend previous results in showing that both parental psychopathology and parental rearing are consistently associated with the risk for offspring SAD. As independent and interactive effects of parental psychopathology and parental rearing may have already manifested in early adolescence, these factors appear crucial and promising for targeted prevention programs.
